数字孪生流域三维数据底板建设研究及应用
Study and application of 3D data baseboard construction in digital twin basin
摘要
Abstract
As a result of basin digital mapping,3D data baseboard is the basis of digital scene construction and intelligent simu-lation iteration.In order to clarify the technical logic,this article systematically elaborates on the positioning,construction tasks,and technical roadmap of the 3D data Baseboard.We elaborate key technologies such as massive data fusion,lightweight data pro-cessing,scene rendering and publishing,data visualization and calculation,and data sharing and co construction during the con-struction process,during which we focus on the technical difficulties,solutions,and specific methods.Based on the above re-search,taking Cao'e River digital twin basin as an example,we construct 3D data baseboard(L2 and L3)based on BIM+GIS and other technologies,and use 3D digital scenes to support the application of visualization models such as"four presets"in the basin.The results have reference significance for similar data baseboard construction.关键词
